Graphite is flammable on contact with magma but will never melt, meaning graphite on fire makes an excellent long-burning flame - a single boulder will burn for about nine and a half months before being consumed. This quality has applications in some fire-based traps.

Graphite is the most common form of carbon under standard Earth temperatures and pressures. It sits around 1.5 on the Mohs scale, making it a very soft substance. Synthetic Graphite is relatively easy to produce via compression.
